With all the attacks on the Koch brothers during the midterm election, please note: "Big Democrat donors outspend GOP by 3-to-1"

From the Pittsburgh Tribune:

For as often as Democrats attack conservative billionaires Charles and David Koch for heavy spending on politics, it's the liberal-minded who shelled out the most cash on the just-completed midterm elections.  

At least, that is, among those groups that must disclose what they raise and spend.
Among the top 100 individual donors to political groups, more than half gave primarily to Democrats or their allies. Among groups that funneled more than $100,000 to allies, the top of the list tilted overwhelmingly toward Democrats — a group favoring the GOP doesn't appear on the list until No. 14.  

The two biggest super PACs of 2014? Senate Majority PAC and House Majority PAC — both backing Democrats.  

In all, the top 10 individual donors to outside groups injected almost $128 million into this year's elections. Democratic-leaning groups collected $91 million of it.  

Among the 183 groups that wrote checks of $100,000 or more to another group, Democrats had a 3-to-1 cash advantage. . . .  Not a single Republican-leaning group cracked the top 10 list of those transferring money to others.  

Overall, for the campaign season that just ended, donors who gave more than $1 million sent roughly 60 cents of every dollar to liberal groups. Among the 10 biggest donors, Democrats outspent Republicans by an almost 3-to-1 margin.  

“They're total hypocrites when it comes to this subject,” said Republican National Committee Chairman Reince Priebus. “They've made a living off campaign talking points when, in reality, they've been raking in more money from millionaire donors than Republicans for quite a while.”  . . .

Note that the list of donors that the Associated Press study provides doesn't include all the money that Michael Bloomberg gave to promote gun control efforts that went overwhelmingly to help Democrats.
